Management and surgical treatment of parathyroid carcinoma: a 6-year experience of a single centre of endocrine surgery unit. Front Endocrinol (Lausanne) 2023; 14:1278178. [PMID: 38027123 PMCID: PMC10656609 DOI: 10.3389/fendo.2023.1278178] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Accepted: 10/16/2023] [Indexed: 12/01/2023] Open
Abstract
Background Parathyroid carcinoma (PC) affects 0.1-0.3% of the general population and represents the rarest malignant neoplasms among endocrinological diseases, comprising less than 1%. The best therapeutic treatment and management methods are still debated in the literature. The aim of this study is to evaluate the management and surgical treatment of parathyroid carcinoma after 6 years of enrolment with the Endocrine Surgery Unit of the University Hospital of Bari. Materials and methods A retrospective observational study was carried out using a prospectively maintained database of patients affected by primary hyperparathyroidism between January 2017 and September 2022. Consecutive patients over 18 years old with a final histopathological finding of PC were included in the study. Patients with secondary or tertiary hyperparathyroidism, parathyroid hyperplasia, and parathyroid adenoma were excluded. All patients underwent follow-up every 6 months for the first 2 years, and annually thereafter. Results In this study, 9 out of 40 patients affected by hyperparathyroidism were included; 6 (66.6%) were female and 3 (33.3%) were male patients, with a median age of 59 years (IQR 46-62). None had a family history of PC. No mortality was recorded while the incidence of recurrence was 22.2%, with a disease-free survival of 8 and 10 months. Parathyroidectomy was performed in five patients, while four patients underwent parathyroidectomy with concurrent thyroidectomy for thyroid goitre. No intraoperative complications were recorded. Open parathyroidectomy was performed with a mini-cervicotomy in seven patients, while two patients underwent robotic surgery. All patients were discharged on the second postoperative day. Conclusion PC represents a great challenge in terms of preoperative diagnosis, management and treatment. A surgical approach represents the first best option for PC in referral endocrine surgery units. The early identification of risky patients should be the dominant goal to plan an appropriate therapy and to perform adequate en bloc surgery.

Abstract
Primary hyperparathyroidism caused by parathyroid carcinoma is extremely rare. Clinically, it is very challenging to differentiate between parathyroid carcinoma and adenoma. The correct diagnosis is made based on the histopathology of the resection specimen. This case report presents a woman in her 40s with body aches, knee joint pain, and fatigue, along with chronic kidney disease. Ultrasonography revealed a large hyperechoic lesion in the left parathyroid gland. Serum calcium, parathyroid hormone, urea, and creatinine levels were increased. The inferior parathyroid gland was surgically removed, and histopathological evaluation confirmed a diagnosis of parathyroid carcinoma. Unfortunately, many patients do not undergo complete resection due to a lack of a correct diagnosis during the initial surgery.

Abstract
Giant parathyroid adenomas (GPA) are a benign cause of primary hyperparathyroidism (PHPT) that might present similarly to parathyroid carcinomas (PC). Rarely, PHPT can present with a parathyroid crisis, a life-threatening decompensation with severe hypercalcemia. A 77-year-old woman presented with lethargy and muscle weakness. Investigation revealed parathyroid hormone-dependent hypercalcemia and an enlarged parathyroid measuring 31x24 mm. The patient was submitted for parathyroidectomy. Histology showed no evidence of malignancy, confirming a GPA. We report a GPA presenting with a parathyroid crisis. The clinical picture mimicked that of a PC. There are no clinical, analytical, or imagiological features pathognomonic of PC.

Abstract
Hyperparathyroidism is a common endocrine disorder characterized by elevated levels of parathyroid hormone and hypercalcemia and is divided into 3 types: primary, secondary, and tertiary. Distinction between these types is accomplished by correlation of clinical, radiologic, and laboratory findings with pathologic features. Primary hyperparathyroidism occurs sporadically in 85% of cases with the remaining cases associated with multiple familial syndromes. The pathologic manifestations of primary hyperparathyroidism include parathyroid adenoma, parathyroid hyperplasia, and parathyroid carcinoma. Recent advances in the understanding of the pathogenesis of parathyroid disease has helped to refine the diagnosis and classification of parathyroid lesions. The identification of multiple clonal proliferations in traditional multiglandular parathyroid hyperplasia has led to the adoption by the World Health Organization (WHO) of the alternate term of primary hyperparathyroidism-related multiglandular parathyroid disease. Additional nomenclature changes include the adoption of the term atypical parathyroid tumor in lieu of atypical parathyroid adenoma to reflect the uncertain malignant potential of these neoplasms. Clinical and morphologic features characteristic of familial disease have been described that can help the practicing pathologist identify underlying familial disease and provide appropriate management. Use of ancillary immunohistochemistry and molecular studies can be helpful in classifying parathyroid neoplasms. Parafibromin has proven useful as a diagnostic and prognostic marker in atypical parathyroid tumors and parathyroid carcinomas. This review provides an update on the diagnosis and classification of parathyroid lesions considering the recent advances in the understanding of the molecular and clinical features of parathyroid disease and highlights the use of ancillary studies (immunohistochemical, and molecular) to refine the diagnosis of parathyroid lesions.

Abstract
Objective To review the features and treatment of parathyroid cancer in our series. Explore the suitable extent of initial surgery and the effect of adjuvant radiotherapy in local recurrence. Methods Seven cases of parathyroid cancer presented from 2014 to 2021. The presenting features, diagnosis, and treatment are presented. Results Only two patients had multiple manifestations of hypercalcemia. Marked hypercalcemia, which was revealed to be an average of 13.9 mg/dl (range from 11.8 mg/dl to 15.8 mg/dl), was observed in four patients (57%). The others' serum calcium levels were in the normal range with an average of 9.9 mg/dl (range from 8.6 mg/dl to 10.8 mg/dl). All seven patients had hyperparathyroidism with an average of 733 pg/ml (range from 113 pg/ml to 3193 pg/ml). En bloc resection was performed in two patients with neighboring structure invasion, and four patients with complete tumor capsules underwent tumor resection with limited resection of the thyroid gland. Postoperative adjuvant radiotherapy appeared unsuccessful for local recurrence. Conclusion High calcium, high PTH, parathyroid occupation by ultrasound, and intraoperative invasion should be considered to have the possibility of parathyroid cancer. Open surgery is recommended and protecting tumor integration is the elementary surgery principle. The initial surgical extent should be decided by the invasion of the tumor. When PC has a local recurrence, the debulking surgery and adjuvant radiotherapy are always fake.

Association of Parathyroid and Differentiated Thyroid Carcinomas: A Narrative Up-To-Date Review of the Literature. Medicina (B Aires) 2022; 58:medicina58091184. [PMID: 36143862 PMCID: PMC9503363 DOI: 10.3390/medicina58091184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 08/24/2022] [Accepted: 08/25/2022] [Indexed: 11/16/2022] Open
Abstract
Aim: Parathyroid carcinoma (PC) is a rare endocrine malignancy that represents 0.005% of all malignant tumors. Associated PC and differentiated thyroid carcinoma (DTC) is an exceptionally rare condition, and the preoperative diagnostics and proper treatment are challenging. Almost all PCs and the majority of DTCs are diagnosed postoperatively, making correct surgical treatment questionable. Specific guidelines for parathyroid and thyroid carcinomas association treatment are lacking. The purposes of our study were to identify the association between parathyroid and thyroid carcinomas, to analyze the available published data, and to evaluate the possible relationship between preoperative diagnostic and surgical decision-making, and outcome-related issues. Material and methods: We performed a literature review of several databases from the earliest records to March 2022, using controlled vocabulary and keywords to search for records on the topic of PC and WDTC pathological association. The reference lists from the initially identified articles were analyzed to obtain more references. Results: We identified 25 cases of PC and DTC association, 14 more than the latest review from 2021. The mean age of patients was 55, with a female to male ratio of about 3:1. Exposure to external radiation was identified in only one patient, although it is considered a risk factor the development of both PC and DTC. The preoperative suspicion of PC was stated by the authors in only 25% of cases, but suspicion based on clinical, laboratory, ultrasound (US), and fine needle aspiration (FNA) criteria could have been justified in more than 50% of them. With neck ultrasound, 40% of patients presented suspicious features both for PC and thyroid carcinoma. Intra-operatory descriptions of the lesions revealed the highest suspicion (83.3%) of PC, but en bloc resection was recommended and probably performed in only about 50% of the cases. Histopathological examinations of the thyroid revealed different forms of papillary thyroid carcinoma (PTC) in most cases. Postoperative normocalcemia was achieved in 72% of patients, but follow-up data was missing in about 25% of cases. Conclusion: Associated PC and DTC is an exceptionally rare condition, and the preoperative diagnostic and treatment of the patients is a challenge. However, in most cases pre- and intraoperative suspicious features are present for identification by a highly specialized multidisciplinary endocrine team, who can thus perform the optimal treatment to achieve curability.

Abstract
Simple Summary Parathyroid carcinoma (PC) is a rare endocrine malignancy with poor outcomes. Surgery remains the mainstay of PC treatment. However, due to the rarity of this malignancy, the optimal extent of PC surgery remains inconclusive, including whether to perform central lymph node dissection (LND). In the present study, we reported the patterns and predictors of cervical lymph node metastasis in PC based on a cohort of 68 PC patients. The results showed that the percentage of cervical lymph node metastasis in PC was 19.4% at initial surgery and 25.0% including reoperations for recurrencies. High-risk Schulte staging and CDC73 abnormalities were identified as risk factors for cervical lymph node metastasis. Central LND should be considered during remedial surgeries performed after previous local resection of PC for patients with high risk factors. Abstract Background: Parathyroid carcinoma (PC) is a rare endocrine malignancy with poor outcomes. Over 60% of PC patients experience repeated disease recurrence or metastasis. The significance of cervical lymph node dissection (LND) for PC remains inconclusive. Methods: PC patients diagnosed at Peking Union Medical College Hospital between 1992 and 2021 were reviewed retrospectively. Clinical data, initial tumor histological staging, parafibromin histochemical staining results, Ki67 index, CDC73 gene mutation status and outcome information were collected systemically. The risk factors for recurrence and lymph node or distant metastasis were explored. Results: Sixty-eight PC patients receiving LND were enrolled. Cervical lymph node metastasis was identified in 19.4% of patients at initial surgery and 25.0% of patients including reoperations for recurrences. The independent risk factor for PC recurrence was a Ki67 index ≥ 5% (HR4.41, 95% confidence interval (CI)1.30–14.95, p = 0.017). Distant metastasis was an independent prognostic factor for PC patient overall survival (HR 5.44, 95% CI 1.66–17.82, p = 0.005). High-risk Schulte staging (p = 0.021) and CDC73 abnormalities (p = 0.012) were risk factors for cervical lymph node metastasis. Conclusion: Most PCs were slow-growing, but lymph node metastasis was not rare. For patients planning to undergo remedial surgery after previous local resection of PC, central LND is suggested for tumors with high-risk Schulte staging or CDC73 abnormalities.

Abstract
INTRODUCTION Atypical parathyroid adenomas (APA) are an uncommon cause of hypercalcemia and comprise a minority of parathyroid adenomas. PRESENTATION OF CASES Case 1 - Egyptian male, 48 years old with history of type 2 diabetes mellitus, incidentally discovered increased serum of calcium level on routine investigation, was diagnosed as PHPT, US and MIBI scan showed large left inferior parathyroid adenoma, focused exploration and excision of the APA was undertaken, histopathology confirmed APA. Case 2 - Egyptian male, 60 years old, cardiac patient with history of diabetes, hypertension and multiple cardiac interventions, had nausea, vomiting, constipation abdominal pain, polyuria, polydipsia, and history of passing renal stones, hypercalcemia workup showed primary hyperparathyroidism (PHPT), MIBI was negative and SPECT scan suggested right inferior parathyroid adenoma, focused exploration and excision of the APA was undertaken, histopathology confirmed APA. DISCUSSION APA are an uncommon cause of hypercalcemia and are responsible for a minority of parathyroid adenomas. Combined US and MIBI and SPECT scans can detect APA. Focused exploration and excision of the APA under general anaesthesia can completely remove the APA. CONCLUSION Awareness of the physician and a high index of suspicion to symptoms or signs that could reflect an underlying PHPT is essential. Yearly biochemical and neck US follow up are required to detect any risk of recurrence or malignancy in the long term.

Abstract
Introduction: Parathyroid carcinoma (PC) is an extremely rare entity, with a frequency of 0.005% of all malignancies. Most data related to this rare disease are limited to case series and a few database studies. We present a large database study that aims to investigate the demographic, clinical, and pathological factors, prognosis, and survival of PC. Methods: Data of parathyroid carcinoma were extracted from the Surveillance, Epidemiology, and End Results (SEER) diagnosed between 1975 and 2016. Results: PC had a slightly higher incidence in men (52.2%, p < 0.005), the majority of cases affected Caucasians (75.4%, p < 0.005), and the mean age at diagnosis was 62 years. Histologically, 99.7% were adenocarcinomas not otherwise specified (p < 0.005), well-differentiated (p < 0.005), and 2−4 cm (p < 0.001) in size among the patients with available data. In cases with staging provided, most PC were organ-confined (36.8%, p < 0.001). Lymph nodes were positive in 25.2% of cases where lymph node status was reported. The main treatment modality was surgery (97.2%), followed by radiation alone (2%), and very few received chemotherapy alone (0.8%), p < 0.005. Five-year follow-up was available for 82.7% of the cases. Those who underwent surgery only or radiation alone had 5-year survivals of 83.8% and 72.2%, respectively (p < 0.037). Multivariable analysis identified tumor size >4 cm, age > 40 years, male sex, Caucasian race, distant spread, and poorly differentiated grade as independent risk factors for mortality (p < 0.001). Conclusion: PC is a very rare tumor mostly affecting Caucasian individuals in the fifth decade. Older age, poor histologic differentiation, and distant metastasis are associated with a worse prognosis. Surgical resection offers the best survival outcome. To better understand the pathogenesis and factors affecting survival, all PC patients should be enrolled in national and international registries.

Abstract
Parathyromatosis is displaced parathyroid tissue in the neck and mediastinum related to prior surgery. Parathyromatosis can be difficult to distinguish from atypical adenoma and parathyroid carcinoma. The aim of this study is to evaluate clinical and morphologic features that may differentiate parathyromatosis, atypical adenoma, and parathyroid carcinoma. Cases of parathyromatosis, atypical adenoma, and parathyroid carcinoma were identified. Index cases were reviewed by consensus for histologic features, including stromal, cytologic/architectural, and invasive features. Ki67 was performed on index cases and scored using the Adsay method. Clinical information was gathered from the electronic medical record. 4 parathyromatosis, 17 atypical adenoma, and 6 parathyroid carcinoma were included. Parathyroid carcinomas were more likely to display coarse chromatin with nucleoli (P = 0.04), infiltrative invasion (P < 0.01), and metastasis (P < 0.01). Only parathyromatosis showed circumscribed invasion. Infiltrative invasion was more common in cases with progression (P = 0.046) and metastasis (P < 0.001). Necrosis and perineural invasion were only present in cases with progression and were more frequent in cases with metastasis (P = 0.079 and P = 0.19, respectively). There were no differences in presence of a fibrous capsule, capsular invasion, intralesional fibrous bands, random endocrine atypia, solid growth, Ki67 index, gland size/weight, serum PTH/calcium levels, and locoregional recurrence rates. There is overlap in the histologic features in parathyromatosis, atypical adenoma, and parathyroid carcinoma. While perineural, vascular, and infiltrative soft tissue invasion should remain diagnostic of malignancy, other atypical features such as solid growth, coarse chromatin with nucleoli, and necrosis should raise concern for recurrence and/or metastasis, and can be present in parathyroid lesions with and without recurrence.

[PMID: 33472651 PMCID: PMC7818751 DOI: 10.1186/s12957-021-02123-7] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 01/05/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Primary hyperparathyroidism is an endocrine pathology that affects calcium metabolism. Patients with primary hyperparathyroidism have high concentrations of serum calcium or high concentrations of parathyroid hormone, or incorrect parathyroid hormone levels for serum calcium values. Primary hyperparathyroidism is due to the presence of an adenoma/single-gland disease in 80-85%. Multiple gland disease or hyperplasia accounts for 10-15% of cases of primary hyperparathyroidism. Atypical parathyroid adenoma and parathyroid carcinoma are both responsible for about 1.2-1.3% and 1% or less of primary hyperparathyroidism, respectively. METHODS We performed a retrospective cohort study and enrolled 117 patients with primary hyperparathyroidism undergoing minimally invasive parathyroidectomy. Histological and immunohistochemical examination showed that 107 patients (91.5%) were diagnosed with typical adenoma (group A), while 10 patients (8.5%) were diagnosed with atypical parathyroid adenoma (group B). None of the patients were affected by parathyroid carcinoma. RESULTS Significant statistical differences were found in histological and immunohistochemical parameters as pseudocapsular invasion (p < 0.001), bands of fibrosis (p < 0.001), pronounced trabecular growth (p < 0.001), mitotic rates of > 1/10 high-power fields (HPFs) (p < 0.001), nuclear pleomorphism (p = 0.036), thick capsule (p < 0.001), Ki-67+ > 4% (p < 0.001), galectin-3 + (p = 0.002), and protein gene product (PGP) 9.5 + (p = 0.038). CONCLUSIONS Atypical parathyroid adenoma is a tumor that has characteristics both of typical adenoma and parathyroid carcinoma. The diagnosis is reached by excluding with strict methods the presence of malignancy criteria. Atypical parathyroid adenoma compared to typical adenoma showed significant clinical, hematochemical, histological, and immunohistochemical differences. We did not find any disease relapse in the 10 patients with atypical parathyroid adenoma during 60 months of follow-up time.

Abstract
Parathyroid carcinoma (PC) is a rare malignancy that poses a diagnostic challenge on histologic examination. We analyzed various clinicopathologic features of PC. Pathology reports and slides were reviewed to evaluate the diagnostic histopathologic features of archived cases of PC from the years of 2004-2018. The study cohort comprised twenty cases of PC. The median age was 49 years (range 21-73 years) with equal gender distribution (M:F = 1:1). Most patients presented with symptoms of hypercalcemia (n = 7, 54%). Serum calcium and serum parathyroid hormone were elevated in all but one patient. The right inferior parathyroid was commonly involved (n = 8/14, 57%). The mean tumor size was 2.4 cm (range 0.8-3.5 cm). On frozen section examination, PC was diagnosed in 8 out of 9 cases. Vascular (n = 19/20, 95%) and soft tissue invasion (n = 10/20, 50%) were the most common characteristic histologic findings. Capsular invasion was identified in all cases. Perineural invasion or metastasis at presentation was absent in all cases. Other histological features noted were intratumoral fibrous bands (70%), nodular growth pattern (70%), moderate nuclear atypia (30%), prominent nucleoli (20%), and necrosis (20%). Regional lymph nodes were negative for metastatic disease in all cases (n = 10). Eight out of 16 patients received adjuvant radiotherapy. Follow-up was available in 16 cases (median 21.5 months). Two patients died of disease. Vascular and soft tissue invasion are the most common diagnostic histologic features of PC. Capsular invasion is important to distinguish PC from its benign counterparts. Intraoperative frozen section examination can be used for accurate diagnosis and surgical management.

Abstract
Intraoperative imaging of living tissue at the cell level by endomicroscopy might help surgeons optimize surgical procedures and provide individualized treatments. However, the resolution of the microscopic image is limited by the motion of living tissue caused by heartbeat and respiration. An active motion compensation (AMC) strategy has been recognized as an effective way to reduce, or even eliminate, the influence of tissue movement for intravital fluorescence microscopy (IVM). To realize the AMC system, a high-speed sensor for measuring the motion of tissues is needed. At present, state-of-the-art commercialized displacement sensors are not suitable to apply in minimally invasive imaging instruments to measure the motion of living tissues because of the size problem, range of measurement or the update rate. In this study, a compact high-speed image-based method for measuring the longitudinal motion of living tissues is proposed. The complexity of the proposed method is the same as that of the traditional wide-field fluorescent microscopy (WFFM) system, which makes it easy to be miniaturized and integrated into a minimally invasive imaging instrument. Experimental results reveal that the maximum indication error, range of measurement and the sensitivity of the laboratory-built experimental prototype is 150 μm, 6 mm and −211.46 mm−1 respectively. Experimental results indicate that the proposed optical method is expected to be used in minimally invasive imaging instruments to build an AMC system.

Abstract
Standardized pathologic reporting for cancers improves patient care and prognostic determination. However, access in many countries is limited. To address this issue, the International Collaboration on Cancer Reporting (ICCR), a not-for-profit organization, has the mission to develop and disseminate standardized data sets for global use. Within endocrine organs, the parathyroid gland has rarely been included in formal pathologic data sets. Utilizing an expert international panel of eleven members, an evidence-based data set was developed for parathyroid carcinoma and atypical parathyroid neoplasms. This data set consists of sixteen core (required) elements viewed as essential for documentation of these conditions. Characterizing parathyroid carcinomas and atypical neoplasms begins with correlative clinical information, the operative procedure, specimens submitted, and site of the disease. The pathologic features essential to document include parathyroid weight, size, classification, and, when a carcinoma, the tumor grade. Histologic grade of parathyroid carcinoma incorporates other core elements including necrosis, mitotic count, perineural invasion, and lymphovascular invasion. Documenting the extent of disease locally into adjacent organs, regionally, and distally is critical for staging. Pathologic staging is now included as part of the American Joint Committee on Cancer 8th edition and is included in this data set. Ancillary studies should be recorded when performed as noncore elements. Standardized pathologic data sets for endocrine organs including the parathyroid gland are now available through the ICCR website. These essential resources enhance international standardization for documenting these rare tumors for both patient care and future guidelines.

Abstract
We present a case of an 80-year-old patient with three concurrent multiple atypical parathyroid adenomas. The patient was managed with bilateral parathyroid exploration and concurrent parathyroidectomy. Postoperative recovery was uneventful. Atypical parathyroid adenomas are a rare entity that are clinically difficult to distinguish from parathyroid carcinoma. Histological characteristics are similar however atypical adenomas lack complete capsular or vascular invasion and cannot be considered malignant. All reported cases of atypical parathyroid adenoma are solitary lesions. We present the first case of multiple concurrent atypical parathyroid adenomas.

Abstract
PURPOSE Minimally invasive parathyroid carcinoma (MIPC) is clinically and biochemically comparable with parathyroid adenoma (PA) though histopathologically differ from PA. MIPC is an intermediate of PA and parathyroid carcinoma (PC). In literature, there is no definite criterion to diagnose MIPC. Our aim was to evaluate and characterize the imaging and biochemical parameters with histological characteristics of MIPC. METHODOLOGY Ten patients with MIPC were recruited from (single centre) Indian PHPT registry (www.indianphptregistry.com) from January 2014 to July 2018. Clinical, biochemical, imaging and histological features of MIPC patients were reviewed. RESULTS The mean age of MIPC patients (n = 10; 3 males) was 39.9 ± 11.3 years (range: 17-50). All patients had an elevated preoperative parathyroid hormone (iPTH) level ranging from 427 to 2138 pg/mL (median: 1328). MIBI scan showed intensely avid and enlarged parathyroid tumours in all patients; LIPT in 6, RIPT in 3 and ectopic mediastinal in 1 with mean size of the tumours was 2.8 ± 1.1 cm. The mean of maximum standardized uptake value (SUVmax) of MIPC in F-18 fluorocholine PET/CT was 6.7 ± 1.1 (range 6.0-8.3). The mean tumour weight was 12 ± 9.5 g (range: 1.09-28). All MIPC patients had identified capsular invasion in 80% and vascular invasion in 50% only but there was no local invasion, lymph nodal or distant metastasis. The mean Ki-67 labelling index was 3.2 ± 2.7 (range 1.1-10). CONCLUSION The study concluded that MIPC patients are less aggressive (on the basis of imaging and histopathological findings) and should be differentiated from parathyroid adenoma and carcinoma.

Parafibromin-deficient (HPT-JT Type, CDC73 Mutated) Parathyroid Tumors Demonstrate Distinctive Morphologic Features. Am J Surg Pathol 2019; 43:35-46.

Abstract
The gene CDC73 (previously known as HRPT2) encodes the protein parafibromin. Biallelic mutation of CDC73 is strongly associated with malignancy in parathyroid tumors. Heterozygous germline mutations cause hyperparathyroidism jaw tumor syndrome,which is associated with a high life-time risk of parathyroid carcinoma. Therefore loss of parafibromin expression by immunohistochemistry may triage genetic testing for hyperparathyroidism jaw tumor syndrome and be associated with malignant behavior in atypical parathyroid tumors. We share our experience that parafibromin-negative parathyroid tumors show distinctive morphology. We searched our institutional database for parathyroid tumors demonstrating complete loss of nuclear expression of parafibromin with internal positive controls. Forty-three parafibromin-negative tumors from 40 (5.1%) of 789 patients undergoing immunohistochemistry were identified. Thirty-three (77%) were external consultation cases; the estimated incidence in unselected tumors was 0.19%. Sixteen (37.2%) fulfilled World Health Organization 2017 criteria for parathyroid carcinoma and 63% had serum calcium greater than 3mmol/L. One of 27 (3.7%) noninvasive but parafibromin-negative tumors subsequently metastasized. Parafibromin-negative patients were younger (mean, 36 vs. 63 y; P<0.001) and had larger tumors (mean, 3.04 vs. 0.62 g; P<0.001). Not all patients had full testing, but 26 patients had pathogenic CDC73 mutation/deletions confirmed in tumor (n=23) and/or germline (n=16). Parafibromin-negative tumors demonstrated distinctive morphology including extensive sheet-like rather than acinar growth, eosinophilic cytoplasm, nuclear enlargement with distinctive coarse chromatin, perinuclear cytoplasmic clearing, a prominent arborizing vasculature, and, frequently, a thick capsule. Microcystic change was found in 21 (48.8%). In conclusion, there are previously unrecognized morphologic clues to parafibromin loss/CDC73 mutation in parathyroid tumors which, given the association with malignancy and syndromic disease, are important to recognize.

Abstract
OBJECTIVE Cystic parathyroid adenoma is a rare cause of primary hyperparathyroidism, but its preoperative diagnosis and management remain inconclusive. METHOD We retrospectively identified patients with cystic parathyroid adenomas who underwent surgery at Peking Union Medical College Hospital. RESULTS Patients with cystic parathyroid adenomas had higher serum intact parathyroid hormone and calcium levels, larger maximum tumor diameter, and lower serum inorganic phosphorus level than did those with solid adenomas. Patients with cystic adenomas were predominantly male, and hypercalcemic crisis and atypical adenomas were common. The accuracy of preoperative localization methodologies was lower in patients with cystic adenomas than in patients with solid adenomas. US-guided fine-needle aspiration was performed in 11 patients. In all patients, the iPTH level in cystic fluid was much higher than that in serum. No sign of recurrence was observed after a median follow-up of 39 months. CONCLUSIONS Cystic parathyroid adenomas may not be as rare as previously reported. FNA may be a safe and feasible localization methodology for patients with inconclusive preoperative localization methodologies. Close follow-up is necessary for patients with cystic parathyroid adenomas, which account for a substantial proportion of atypical adenoma cases.

BACKGROUND/AIM Parathyroid carcinoma is a rare clinical entity, which represents one of the main reasons, why surgery should be performed in specialized centres. Preoperatively, it is very difficult to distinguish between benign and malignant hyperparathyroidism. PATIENTS AND METHODS During the years 1996-2016, we performed 2,220 operations in 2,075 patients with a diagnosis of primary hyperparathyroidism. RESULTS Among these 2,220 operations, there were 16 operations for parathyroid carcinoma. These 16 operations, including reoperations, were performed in four patients. Two patients had no reoperation, but another 2 patients required 14 reoperations in total. Parathyroid carcinoma was described in 0.2% of all patients with a diagnosis of primary hyperparathyroidism. The number of operations was 0.73% of all operations of primary hyperparathyroidism in years 1996-2016. CONCLUSION Prognosis of parathyroid carcinoma is quite favourable, patients evidence a long-term survival rate after the primary operation. However, every reoperation increases the number of possible complications, including recurrent laryngeal nerve injury.

Abstract
BACKGROUND Parathyroid carcinoma (PC) is rare and diagnostically challenging. Reported outcomes are rather poor and the incidence might be increasing. MATERIAL AND METHODS We performed a nationwide study on all cases (n= 32) diagnosed in 2000-2011 in Finland, and compared clinical and histopathological characteristics and outcome to atypical parathyroid (APA; n= 28) and parathyroid adenomas (PA; n= 72). The incidence in years 1955-1999 was compared to that in 2000-2013. RESULTS Preoperatively, calcium and parathyroid hormone concentrations were higher in PC compared to APA and PA (1.76, 1.56 and 1.44 mmol/l, p < .001; and 989, 355 and 160 μmol/l, p < .001, respectively). Calcium was ≤1.77 mmol/l for all PAs. Hospitalization (44% vs. 22% and 3%, respectively, p = .01), renal (50% vs. 48% vs. 22%, respectively, p = .01) and bone (47% vs. 15% vs. 38%, respectively p = .002) manifestations were more common. PC and APA tumors were larger than PA (p < .001). Histopathological characteristics of PC compared to PA are increased mitotic activity (p= .001), chief cells (p = .003), diffuse growth pattern (p < .001), higher Ki67 (p< .001) and negative parafibromin (p < .001). One PC (1/18) and one APA (1/16) patient had a CDC73 mutation. After 6.7 (2-13.9) years of follow-up, 9.4% of PC had residual, 21% recurrent disease and 12.5% died of disease. Overall mortality did not differ between subgroups (p = .094). Recurrent PC was characterized by vascular invasion, lymph node metastases, high mitotic activity, necrosis and negative parafibromin. Incidence increased from 1.42 (range 0.52-2.14) to 7.14 (range 3.42-10.38)/10.000.000/years; (p < .001). CONCLUSIONS PC associates with severe primary hyperparathyroidism and must be suspected if calcium ≥1.77 mmol/l. The prevalence of CDC73 germline mutations in PC and APA in Finland is 6%. PC has distinct histopathological characteristics and its incidence has increased over the past decades.

Abstract
SUMMARY Parathyroid carcinoma is an extremely rare disorder with little treatment options. It could be misdiagnosed in medical centers with little experience in management of such cases. Our clinical case shows that the initial misdiagnosis of a parathyroid carcinoma in a young woman has led to the development of multiple lung metastases, thus making its treatment hardly possible. Initiation of treatment with sorafenib - a multi-kinase inhibitor approved for treatment of different types of cancer but not parathyroid carcinoma - has led to a significant decrease in the size of lung metastases and has prevented the progression of hyperparathyroidism, which is usually severe in cases of parathyroid carcinoma. The detection of a germline CDC73 mutation in this patient has raised additional concerns about the necessity of periodic screening for early detection of renal, jaw and uterine lesions. LEARNING POINTS Diagnosis of parathyroid carcinoma may be challenging due to the absence of reliable diagnostic criteria. Thus, thorough histological examination is needed using immunohistochemical staining of resected tissue in suspicious cases. CDC73 genetic testing should be considered in patients with parathyroid carcinoma.Sorafenib may be a promising treatment of patients with parathyroid carcinoma with distant metastases.

Abstract
It is a challenge to distinguish parathyroid carcinoma (PTCA) from benign parathyroid lesions without recurrence or metastasis. Parafibromin immunohistochemical (IHC) staining had been described for the diagnosis of PTCA. But great variations existed in the reported sensitivity and specificity among different studies. We conducted a meta-analysis to summarize the diagnostic accuracy of parafibromin staining for PTCA. Published studies from Pubmed, Embase, and Cochrane Library were searched using the combination of terms "parafibromin," "CDC73," "HRPT2," and "parathyroid." Pooled sensitivity and specificity with 95 % confidence interval (CI) were calculated and the summary receiver operator characteristic (SROC) curves were constructed. The heterogeneity among included studies was evaluated and possible reasons were explored by meta-regression. A total of 10 studies including 202 patients with PTCA were finally enrolled in this meta-analysis. For parafibromin staining, sensitivity varied from 29 to 100 % (pooled estimate of 68 %; 95 % CI 49-82 %) and specificity ranged from 61 to 100 % (pooled estimate of 95 %; 95 % CI 85-98 %). The AUC for parafibromin staining was 0.91 (95 % CI 0.88-0.93). A significant heterogeneity was observed among included studies. According to meta-regression analysis, the scoring criteria and parafibromin antibody used in IHC were the covariates influencing the sensitivity. And the specificity decreased if atypical parathyroid adenomas were included in the control groups. The specificity of parafibromin staining was satisfactory for diagnosis of PTCA, while the sensitivity was limited. We suggested that a standardized IHC protocol and scoring system criteria should be applied in future studies to improve the diagnostic performance of parafibromin staining.

Abstract
BACKGROUND Parathyroid cancer has a poor mid-term prognosis, often because of local recurrence, observed in half of all patients. Modern diagnostic workup increasingly enables a preoperative diagnosis of parathyroid cancer. There is limited evidence that more comprehensive oncologic surgery can reduce the risk of local recurrence. This study aims to identify the best specific surgical approach in parathyroid cancer. METHODS This observational cohort study comprises 19 consecutive patients who had undergone oncologic or nononcologic resection for parathyroid cancer. Baseline parameters were compared by using univariate analysis; outcomes were assessed by χ (2) testing and Kaplan-Meier statistics. RESULTS Fifteen of 19 patients were primarily operated on in our tertiary center between 1996 and 2013, and four were referred for follow-up because of their cancer diagnosis. Patient cohorts defined by histologic R-status were comparable for established risk factors: sex, calcium levels, low-risk/high-risk status, and presence of vascular invasion. Oncologic resections were performed in 13 of 15 patients primarily treated in the center and 0 of 4 treated elsewhere (χ (2) = 5.6; p < 0.01). R0 margins were achieved in 11 of 13 (85 %) undergoing oncologic resection and 1 of 6 (17 %) undergoing local excision (χ (2) = 8.1; p < 0.01). R0 margins and primary oncologic resection were associated with higher disease-free survival rates (χ (2) = 7.9; p = 0.005 and χ (2) = 4.7; p = 0.03, respectively). Revision surgery achieved R0 margins in only 2 of 4 (50 %) of patients. CONCLUSIONS In parathyroid cancer, a more comprehensive surgery (primary oncologic resection) provides significantly better outcomes than local excision as a result of reduction of R1 margins and locoregional recurrence.

Abstract
Parathyroid carcinoma has always been difficult to diagnose pathologically. In fact, most parathyroid tumors which are classified as carcinoma do not recur after excision, and most parathyroid tumors which actually metastasize or recur repeatedly in the neck are not recognized as malignant at first presentation. In 2002, germline HRPT2 (also known as CDC73) mutation was reported as the cause of hyperparathyroidism-jaw tumor (HPT-JT) syndrome, an autosomal dominant hereditary tumor syndrome associated with a lifetime risk of parathyroid carcinoma approaching 15 %. Subsequently, bi-allelic inactivation or mutation of HRPT2 has been reported in the majority of parathyroid carcinomas that actually behave in a malignant manner but very rarely in sporadic benign parathyroid disease. Furthermore, germline testing for HRPT2 mutation in patients presenting with parathyroid carcinoma often identifies occult HPT-JT syndrome even in the absence of a family history or other syndromic manifestations. HRPT2 mutation testing is not readily available, and loss of expression of parafibromin (the protein encoded by HRPT2) as determined by immunohistochemistry has been used as a surrogate marker of HRPT2 mutation. Immunohistochemistry for parafibromin can be technically difficult and has been deployed by different investigators with variable enthusiasm and success. However, proponents have found immunohistochemistry for parafibromin useful to definitively confirm a pathological diagnosis of parathyroid carcinoma, predict a worse outcome in definite parathyroid carcinomas, triage formal genetic testing for HPT-JT syndrome, and predict the outcome of histologically atypical parathyroid adenomas.

Abstract
BACKGROUND The histopathological criteria for carcinoma proposed by the World Health Organization (WHO) are imperfect predictors of the malignant potential of parathyroid tumors. Negative parafibromin (PF) and positive protein gene product 9.5 (PGP9.5) staining are markers of CDC73 mutation and occur commonly in carcinoma but rarely in adenomas. We investigated whether PF and PGP9.5 staining could be used to predict the behavior of atypical parathyroid adenomas--tumors with atypical features that do not fulfill WHO criteria for malignancy. METHODS Long-term outcomes were compared across four groups: group A, WHO-positive criteria/PF-negative staining; group B, WHO(+)/PF(+), group C; WHO(-)/PF(-); and group D, WHO(-)/PF(+). RESULTS Eighty-one patients were included in the period 1999-2012: group A (n = 13), group B (n = 14), group C (n = 21), and group D (n = 33). Mortality and recurrence rates, respectively, for group A were 15 and 38%, for group B 7 and 36%, for group C 0 and 10%, and for group D 0 and 0%. The PGP9.5(+) ratios for groups A to D were 85, 78, 71, and 12%, further informing prognosis. Five-year disease-free survival for groups A to D were 55, 80, 78, and 100%, respectively. Tumor recurrence was significantly associated with PF (p = 0.048) and PGP9.5 (p = 0.003) staining. CONCLUSIONS Although WHO criteria are essential to differentiate parathyroid carcinoma from benign tumors, the presence of negative PF staining in an atypical adenoma predicts outcome better, whereas PF-positive atypical adenomas do not recur and can be considered benign. PF-negative atypical adenomas have a low but real recurrence risk and should be considered tumors of low malignant potential.

Abstract
BACKGROUND Cure of parathyroid carcinoma (PC) requires initial en bloc resection, including resection of all tumor-bearing tissue, with hemithyroidectomy and dissection of the central lymph node compartment. Unfortunately, no reliable preoperative criteria have yet been assessed to indicate a high likelihood of PC. Thus, the aim of the present study was to develop a formula to indicate preoperatively the presence of PC. METHODS A prospective database of 1,363 patients with primary hyperparathyroidism (pHPT) was screened for patients with PC. Age, gender, surgical procedures, laboratory data, and follow-up results were evaluated and compared to a group of patients with benign pHPT. Based on preoperative serum calcium (Ca) and parathyroid hormone (PTH) levels, as well as patients' age at the time of diagnosis, a formula was developed by a multivariate logistic model that estimates the individual risk for PC. RESULTS Between 1987 and 2008, 19 patients with PC were identified. Ca (3.8 ± 0.3 vs 2.9 ± 0.3 mmo/l; p = 0.0002) and PTH levels (1,250 ± 769 vs 194 ± 204 pg/ml; p = 0.0030) were significantly higher in patients with PC than in those with benign pHPT. Patients with PC were also significantly younger than patients with benign pHPT (48.9 ± 12.1 vs 59.1 ± 13.8 years; p < 0.05). With a ≥5 % probability that a given patient suffered from PC, the sensitivity and specificity to identify the disease were 100 and 30 %, respectively, with the new Ca, PTH, and age based logarithmic formula. CONCLUSIONS The new logarithmic formula can be used to calculate the individual risk for PC. If the calculated individual risk exceeds 5 %, en bloc resection seems to be justified to provide long-term cure in case of PC.

Abstract
In the last few years, causative genes have been identified for most of the familial hyperparathyroidism conditions. Germline mutations in the tumour suppressors multiple endocrine neoplasia type 1 (MEN1) and hyperparathyroidism 2 (HRPT2) provide a molecular diagnosis of multiple endocrine neoplasia type 1 and hyperparathyroidism jaw tumour syndrome, respectively. Germline mutations in the proto-oncogene RET (rearranged during transfection) provide a molecular diagnosis of multiple endocrine neoplasia type 2. Germline mutations of both MEN1 and, less frequently HRPT2, have been found in familial isolated hyperparathyroidism. A molecular diagnosis can now be incorporated into the management of patients with these conditions, however, the ease of diagnostics and value of genetic information in the context of clinical screening and early surgical intervention varies between these disorders. This review focuses on familial hyperparathyroidism and its known causative genes in the setting of neoplastic syndromes, with particular discussion of recent developments in the molecular diagnosis of parathyroid carcinoma.

Abstract
Parathyroid carcinoma, although a rare cause of primary hyperparathyroidism, carries a significant morbidity and mortality from severe symptomatic hypercalcaemia and related complications. We report a case where the diagnosis was not considered from the outset and review the current clinical and histopathological markers available to assist in the diagnosis of parathyroid carcinoma.

Abstract
Primary hyperparathyroidism (P-HPT) is a common endocrine disorder that occurs as a result of adenomas (80-85%), hyperplasias (10-15%) or carcinomas (<1%) of the parathyroid glands. Molecular genetic analyses of heritable P-HPT syndromes have provided considerable insight into the understanding of sporadic parathyroid tumors and hyperplasias. This review will focus on the criteria for classification of parathyroid proliferative disorders and will highlight our understanding of these lesions at the molecular level. Advances in radiological imaging techniques together with the rapid intraoperative parathyroid hormone assay will be reviewed with respect to current treatment approaches for P-HPT.

Abstract
BACKGROUND The best surgical approach to parathyroid cancer is disputed. Recommendations vary and are built on incoherent evidence. High rates of recurrence and death require an in-depth review of underlying findings. METHODS This retrospective study includes 11 patients with parathyroid cancer who underwent surgery with central and/or lateral neck dissection by a single surgeon between 2005 and 2010. The diagnosis was based on histopathological criteria in all patients. Patterns of lymph node and soft tissue involvement of these and formerly reported patients were analysed based on full-text review of all published cases of parathyroid cancer. RESULTS In this series only 1 of 11 patients (9.1%) manifested lymph node metastasis. In the literature, lymph node metastases have been reported in only 6.5% of 972 published patients, or in 32.1% of the 196 in whom lymph node involvement was assessed by the authors. They were, with few exceptions, localised in the central compartment. Recurrence in soft tissue is more frequent than in locoregional lymph nodes. CONCLUSION Oncological en bloc clearance of the central compartment with meticulous removal of all possibly involved soft tissues, including a systematic central lymph node resection, may improve outcomes and should be included in the routine approach to the suspicious parathyroid lesion. There is no need for a prophylactic lateral neck dissection.

Abstract
BACKGROUND Risk for atypia and carcinoma in large parathyroid tumors is not known. Atypia and carcinoma were determined in small (<2 g) and large (≥2 g) tumors in patients undergoing parathyroidectomy for primary hyperparathyroidism. METHODS The study was a retrospective analysis of a 5-year prospective database. Tumor weight, histopathology, age, gender, calcium, and parathyroid hormone levels were registered. Patients with 4-gland disease were not included. RESULTS Among 353 parathyroid tumors, 313 weighed <2 g and 40 weighed ≥2 g. There was no difference in age between groups. Patients with large tumors were more frequently men and had higher calcium and parathyroid hormone levels. Atypia was found in 4 of 313 (1.3%) and 7 of 40 (17.5%) small and large tumors, respectively (P < .05). Corresponding figures for carcinoma were 1 of 313 (.3%) and 2 of 40 (5.0%) (P < .05). CONCLUSIONS Large parathyroid tumors have increased risk for atypia and carcinoma. Even so, most large parathyroid tumors are benign.

Abstract
Hyperparathyroidism 2 (HRPT2) gene mutations underlie hereditary and sporadic forms of primary hyperparathyroidism (PHPT), and the encoded product parafibromin has been established as a marker for facilitating parathyroid tumour classification. HRPT2 mutations and reduced nuclear expression of parafibromin are readily observed in parathyroid carcinomas but rarely in benign tumours, thereby aiding the identification of malignant PHPT. Recently, parafibromin has been shown to localize to the nucleolar compartment, and nucleolar parafibromin exhibits tumour-suppressive properties in vitro. In this study, nucleolar parafibromin immunoreactivity was assessed by high-power magnification microscopy in 82 parathyroid tumours previously analysed for nuclear parafibromin, including 23 carcinomas, 16 atypical adenomas, and 43 adenomas. Absent nucleolar expression was evident in three carcinomas and in one atypical adenoma, which also showed expression of nuclear parafibromin in all or subsets of the tumour cells. All three carcinomas carried HRPT2-inactivating mutations predicted to abolish the three nucleolar localization signals of parafibromin. The demonstrated absence of nucleolar parafibromin in three carcinomas with HRPT2 mutations suggests that parafibromin exhibits nucleolar tumour suppressor properties also in vivo, and disruption of nucleolar localization might propel parathyroid tumorigenesis independent of nuclear parafibromin expression. The loss of nucleolar staining in the presence of nuclear parafibromin suggests that parafibromin immunoreactivity should also be assessed in the nucleoli, as the sensitivity for the detection of malignant and atypical PHPT is increased compared to scoring of nuclear parafibromin alone.
